Definitions

  • Exemplary embodiments of the present invention relate to an oscillating tissue dissector.
  • Liposuction refers to the surgical removal of adipose tissue from fat deposits by agitation and suction.
  • a cannula which may be a stainless steel tube having one or more holes in its distal end, is inserted into an incision and positioned into adipose tissue, between the dermal layers and the underlying muscle tissue.
  • a suction device is attached to the proximal end of the cannula, i.e., the end of the cannula held by the user.
  • a cannula is moved through adipose tissue in a back-and-forth manner, to create tunnels within the adipose tissue.
  • This back-and-forth movement may be enhanced by using a vibration device, as the fat is suctioned by the suction device through the cannula, decreasing the volume of the adipose tissue.
  • incisions may be made during a liposuction procedure with the incisions being linear incisions or adits and are typically 3 mm to 20 mm in length or diameter, respectively. Ideally, incisions are as small as possible in attempt to make them less visible.
  • Liposuction may take multiple hours to perform with a conventional cannula, and multiple liposuction techniques are currently in use, including laser-assisted liposuction (LAL), power-assisted liposuction (PAL), ultrasonic assisted liposuction (UAL), and water jet assisted liposuction.
  • LAL laser-assisted liposuction
  • PAL power-assisted liposuction
  • UAL ultrasonic assisted liposuction
  • water jet assisted liposuction water jet assisted liposuction.
  • a larger incision is generally required. Trauma to the skin during UAL procedures, due to local heating caused by the ultrasonic vibrations can cause damage. Further, many conventional cannulae may cause bruising, damage to connective tissue, discomfort, pain, scarring, swelling, and tenderness. Additionally, the motion of conventional cannulae through the adipose tissue may require not only manual dexterity but also physical stamina, due to the length of the operation and the force that must be applied to guide the cannula within tissue.
  • tissue dissector that does not include a cannula.
  • Exemplary embodiments of the present invention provide for a tissue dissector that may more efficiently dissect adipose tissue with less damage to surrounding tissue, blood vessels, and nerves, while being able to be inserted into a relatively small surgical incision.
  • An exemplary embodiment of the present invention provides a tissue dissector that includes: a tube having a proximal end and a distal end; a rod disposed within the tube, ribs attached to the rod and extending outside of the tube; a housing disposed at the proximal end of the tube; an actuator disposed in the housing, to rotationally oscillate the rod with respect to the tube; and a first seal disposed around the rod, to prevent fluid from entering the tube.
  • a standard suction cannula may be used to aspirate some or all of the fatty tissue. Any remaining fatty tissue remains viable, as it has not been subjected to laser irradiation or ultrasound. The remaining tissue can be sculpted into a desired shape.
  • FIG. 1 illustrates a sectional view of a tissue dissector, according to an exemplary embodiment of the present invention.
  • FIGS. 2A , 2 B, 2 C, and 2 D illustrate top and side views of ribs of a tissue dissector, according to exemplary embodiments of the present invention.
  • FIG. 3A illustrates sectional view of a tissue dissector, according to an exemplary embodiment of the present invention.
  • FIG. 3B illustrates a perspective view of a tube of the tissue dissector of FIG. 3A .
  • FIGS. 4A , 4 B, 4 C, and 4 D illustrate the operation of an actuator of the tissue dissector of FIG. 2
  • FIG. 1 is a cross-sectional view showing a tissue dissector 100 , according to a first exemplary embodiment of the present invention.
  • the tissue dissector 100 has a proximal end 104 and a distal end 105 .
  • the tissue dissector 100 includes a tube 102 , a rod 108 that extends through the tube 102 , and ribs 110 .
  • the ribs 110 are connected to the distal end the rod 108 , which is exposed outside of the tube 102 .
  • the ribs 110 may be formed of a metal, such as stainless steel.
  • the ribs 110 may be attached to the rod 108 in any suitable manner.
  • the ribs 110 may be welded to the rod 108 .
  • the ribs 110 may be circular in cross-section, i.e., wire-shaped.
  • the ribs 110 may also be rectangular in cross-section, i.e., ribbon-shaped, ovoid in cross-section, or triangular in cross-section.
  • the present invention is not limited to any particular type of rib shape.
  • FIGS. 2A , 2 B, 2 C and 2 D illustrate top and perspective views of rods 108 having various numbers of the ribs 110 attached thereto, in various configurations.
  • FIG. 2A instead of the two ribs 110 as shown in the embodiment of FIG. 1 , four ribs 110 are attached to the rod 108 .
  • the ribs 110 are attached to the rod 108 such that the ribs 110 have a single radius of curvature.
  • the ribs 110 are attached to points on the rod 108 that are disposed on a line extending along the length of the rod 108 .
  • three ribs 110 are attached to the rod 108 .
  • the ribs 110 are attached to the rod 108 such that the ribs 110 have two radii of curvature.
  • the attachment points of the ribs 110 to the rod 108 are not disposed on a line extending along the length of the rod 108 .
  • two ribs 110 are attached to the rod 108 .
  • the ribs 110 are ribbon-shaped, in contrast to the wire-shaped rods 110 of FIGS. 1 , 2 A, and 2 B.
  • the ribs 110 of FIG. 2C are attached to the rod 108 , such that the ribs 110 have two radii of curvature.
  • ribs 110 are attached to the rod 108 .
  • the ribs 110 are attached to the rod 108 in positions similar to those shown in FIG. 2A .
  • adjacent ones of the ribs 110 are also bent so as to contact one another at contact points 111 , thereby creating second radii of curvature. Due to the contact points 111 , the rigidity of the ribs 110 is increased.
  • ribs 110 may be attached to the rod 108 , and the ribs may have more than one radius of curvature. Additionally, a combination of fused and un-fused ribs 110 may be used. However, as a general principal, the ribs 110 should be symmetrically attached to the rod 108 , such that the resultant structures are balanced when oscillated, as discussed below.
  • the tube 102 may be formed of a rigid material, such as stainless steel or the like.
  • the tube 102 may be from about 200 to about 400 mm long and from about 3 to about 5 mm in diameter.
  • the tube 102 may be 300 mm long and may have a diameter of about 4 mm.
  • the tube 102 is substantially thinner than a conventional liposuction cannula, since the tube 102 is not used to remove adipose tissue.
  • the rod 108 may be formed of a rigid material or a flexible material having a high torsional rigidity.
  • the rod 108 may be made of a metal, plastic, or a composite material.
  • the rod 108 is formed of stainless steel.
  • a seal 106 is disposed around the rod 108 at the distal end of the tube 102 .
  • the seal 106 prevents fluid from entering the tube 102 .
  • the seal 106 may be, for example, a rubber or silicon gasket.
  • the seal 106 may include a bearing that prevents motions of the rod 108 from being transferred to the tube 102 .
  • a housing 120 is connected to the proximal end of the tube 102 .
  • the housing 120 may be shaped to operate as a handle.
  • a transmission 112 , an actuator 114 , and a controller 116 are disposed in the housing 120 .
  • the actuator 114 oscillates the rod 107 via the transmission 112 and under the control of the controller 116 .
  • the actuator 114 is connected to the transmission 112 by a drive shaft 113 .
  • the actuator 114 rotates the drive shaft 113 , and the transmission 112 converts the rotational motion of the drive shaft 113 into an oscillating motion.
  • oscillation refers to a non-rectilinear (rotational) reciprocation.
  • the transmission may rotate the rod 108 clockwise and counter clockwise in, for example, a 30 degree arc.
  • the present invention is not limited thereto, as the rod 108 may be oscillated in arcs of from 20 degrees to 40 degrees.
  • the operation of the actuator 114 is controlled by the controller 116 .
  • the controller may be connected to a power source (not shown) or may include a power source.
  • the power source may be an AC voltage source or a rechargeable battery.
  • the controller may vary the amount of current supplied to the actuator 114 , in order to vary the amount of torque produced by the actuator 114 , as discussed below.
  • the actuator 114 may be an electric motor that operates using a DC voltage or an AC voltage, depending on the type of power supply.
  • the controller 116 may include a central processing unit. If the actuator 114 operates using a DC voltage, the controller 115 may include a power rectifier to convert an AC voltage into a DC voltage.
  • tissue dissector 100 is inserted into a patient, and the oscillating ribs 110 impact target tissues, thereby dissecting the tissues.
  • the tissue may be adipose tissue and/or fibrous tissue, such as, lipomas, abnormal collections of fatty tissue e.g., Buffalo hump deformities, gynecomastia (abnormal male breast deformity) tissue, and the like.
  • the ribs 110 are formed of a flexible material, the ribs 110 maybe bent towards the rod 108 when the ribs 110 encounter fibrous tissue. As a result, the torque applied by the ribs 110 to such tissue increases, in accordance with the amount of bending. As a result, the force applied to such tissue may be automatically increased, thereby allowing the tissue dissector 100 to breakup fibrous tissue. In addition, the ribs 110 can be bent during insertion into a patient, to decrease the size of a corresponding incision.
  • the controller 116 can detect the presence of fibrous tissue by, for example, monitoring the resistance encountered by the actuator 114 . In such circumstances, the controller 116 can increase the amount of current applied to the actuator 114 , to thereby increase the torque applied to the ribs 110 . According to other embodiments, the torque applied to the ribs 110 can be manually controlled.
  • the tube 102 Since the tube 102 is isolated from the movement of the rod 108 by the seal/bearing 106 , the tube 102 does not oscillate during tissue dissection. As such, friction between the tube 102 and non-target tissue, for example skin, is greatly decreased. Accordingly, friction burns and/or bruising can be substantially reduced. In addition, the tissue dissector 100 is easier and less strenuous to use, since the handle is also isolated from the movement of the rod 108 .

  • FIG. 3B is a perspective view of a tube 202 shown in FIG. 3 .
  • the tissue dissector 200 is similar to the tissue dissector 100 shown in FIG. 1 , thus, only the differences therebetween will be described in detail.
